Abstrakt:	Objective: The objective of this study was to determine whether cardiovascular disease (CVD) risk factors and stress hormones are associated with cognitive performance in Mexican adolescents. Methods: This was a cross-sectional study including 139 Mexican adolescents 10-14 years old. Participants were divided into three categories: 0, 1-2, and ≥3 CVD risk factors. These factors included: high-density lipoprotein-cholesterol (HDL-C) <40 mg/dl; waist circumference (WC) ≥90th percentile for age and sex, systolic or diastolic blood pressure ≥90th percentile for age, sex, and height; and triacylglycerols (TGs) ≥110 mg/dl. Low-density lipoprotein-cholesterol (LDL-C), very low-density lipoprotein-cholesterol (VLDL-C), total cholesterol, cortisol, and plasma catecholamines were measured as well. Furthermore, attention, memory, and executive functions were evaluated using a validated test for Spanish-speaking individuals (Neuropsi). Results: Adolescents in the three risk categories did not show significant differences in Neuropsi test performance tasks; however, they presented different lipid and plasma norepinephrine concentrations. TG and VLDL-C were inversely associated with memory (r = -0.19, **p < .01). Multivariate regression analysis showed consistently that TG/HDL-C ratio was inversely related to attention-memory general score (standardized β = -0.99, t = -2.30, p = .023), memory (standardized β = -0.83, t = -2.08, p = .039), and attention-executive functions (standardized β = -1.02, t = -2.42, p = .017). Plasma epinephrine levels presented an inverse and weak relation to the attention-executive functions score (standardized β = -0.18, t = -2.19, p = .030). Conclusions: Cognitive performance is not completely dependent on the accumulation of risk factors, but instead on the combination of strong predictors of CVD like waist to height ratio, TG/HDL-C, and VLDL-C. Plasma norepinephrine and epinephrine have a stronger association with cognition and CVD risk than dopamine and cortisol.
